OPERATING ANOMALY
1) Clean or replace it.
2) Check all smoke circuits inside the boiler
and the chimney.
3) Replace the control-box.
4) To be cleaned.
1) Check the circuit completely.
2) Replace them.
3) Connect correctly.
4) Replace it.
5) Adjust them to the prescribed position.
6) Clean or, if necessary, replace them.
1) Check the feeder line.
2) Repair or replace it.
3) Check the suction pipe.
4) Fill with fuel.
5) Open it.
6) Disassemble and clean it completely
7) Invert a phase in the input switch.
1) Increase the value or wait for them to close by
natural decrease in temperature or pressure.
2) Replace it.
3) Close the contact of the switches or wait for
voltage to be supplied again.
4) Check thermo-stat connections.
5) Replace it.
1) Bring it to the expected value.
2) Decrease combustion air.
3) Clean or replace it.
4) Discharge it from the tank by using a suitable
pump (never use the burner pump to carry out this
operation).
1) Increase combustion air.
2) Clean or replace it.
3) Clean them.
4) Bring it to the prescribed value.
TYPE OF IRREGULARITY
PROBABLE CAUSE
RIMEDY
The controll-box stops with fl ame
(red light on)
The failure is limited to the fl ame-
controlling device.
The control-box stops the burner
with fuel spraying
but no fl ame (red light on).
The control-box stops the burner
without spraying
fuel (red light on).
The burner does not start
Defective fl ame with sparks.
Not well-shaped fl ame
with smoke and soot.
1) Photoresistance is cut off or dirty with smoke.
2) Boiler fouled
3) Photoresistor circuit failure
4) Dirty disk or mouth.
1) The ignition circuit is broken.
2) The ignition transformer cables have dried over
time.
3) The ignition transformer cables are
not well connected.
4) The ignition transformer is cut off.
5) The electrode faces are not at theright distance.
6) Electrodes discharge to earth since they are
dirty or with a cracked insulation: also check
under the clamps fastening the insulating
materials.
1) There is one phase missing.
2) Insuffi cient electric motor.
3) Light-oil does not reach the pump.
4) No light-oil inside the tank.
5) Closed gate-valve in suction pipe.
6) Clogged nozzle.
7) Motor rotating in the oppositedirection as that
indicated by the arrow.
1) Open contact in (Boiler or room)
thermo-stats or pressure-switches.
2) Short-circuited photo-resistance.
3) There is no voltage because of the an open con-
tact in the main switch or the meter overload-
release, or no voltage in the line.
4) The thermo-stats line was not carried out
according to the diagram or thermo-stats did not
close their contacts.
5) Failure inside the control-box.
1) Spraying pressure is too low.
2) Too much combustion air.
3) Insuffi cient nozzle since it is dirty or worn out.
4) Water in fuel.
1) Insuffi cient combustion air.
2) Insuffi cient nozzie since it is dirty or worn out.
3) Clogged boiler pipe or chimney.
4) Low spraying pressure.
